This workshop resulted in the publication of Marine and Coastal Protected Areas: In response to the growing awareness of problems in marine ecosystems, the World Wilderness Congress and the IUCN passed resolutions that established a policy framework for marine conservation.
Two international conventions came into force inwhich greatly increased both the obligations of nations to create MPAs in the cause of conservation and their rights to do so. Although the United States has not ratified either convention, there is considerable agreement, at least in principle, with many recommendations of the two conventions, and the components of treaties in force often become customary international law.
UNCLOS establishes duties and rights of nations to establish exclusive economic zones EEZs extending nautical miles from baselines near their coasts. While facilitating the establishment and management of MPAs outside a country's 3-mile territorial waters, UNCLOS forbids interference with freedom of navigation by vessels from other countries.
CBD increases the obligations of signatory nations to protect biodiversity, including biological productivity. There has been considerable progress in establishing MPAs over the past three decades.
Inthere were MPAs in 27 nations. Bythe number had expanded tenfold to at least 1, MPAs in many nations, with numerous other proposals under consideration Kelleher et al. In addition, many military reservations restricted for other purposes have served over time as de facto MPAs.
In the s, increased interest in marine sciences led to the establishment of small scientific research reserves. For example, the Friday Harbor Laboratory Washington State designated the Marine Biological Preserve in but had limited authority for enforcement.
The foregoing history captures the character but not the detail of MPA designations in the United States up until In addition, areas that have fishing restrictions zoning with respect to gear, season, bycatch reduction, and other factors also may be considered types of marine protected areas, encompassing considerable portions of the U.
National parks presently engaged in reducing or eliminating fisheries e.
Few of the national marine sanctuaries have policies to curtail or control fishing, although more areas may be designated with restrictions on fishing activities as the sanctuaries develop new general management plans Davis, A comprehensive review of each of the many types of marine reserves and the legal and institutional frameworks for their management has not been performed nationally, although efforts to inventory MPAs in some areas have been completed McArdle, [California]; Murray and Ferguson, ; Mills, ; Robinson, ; [Washington State] or are under way Marine Fish Conservation Network and Center for Marine Conservation, The following sections present a brief review of the major types of MPAs in the United States, with respect to legislated purpose, management, and attainment of goals.
Also included are laws that promote protection of marine habitats or that prescribe management conditions for areas surrounding MPAs Table Criteria for Evaluation Analysis of the current system of MPAs is constrained to a qualitative rather than a quantitative evaluation by the limited availability of data.
